File Selection Dialog
Using the TixFileSelectDialog Widget
An example of using the TixFileSelectDialog widget is in figure 5-1
. At line 1, we create a TixFileSelectDialog widget and set
the title of the dialog to ``Select A File'' using the
-title
option. We also use the
-command
option to specify that the
procedure
selectCmd
should be called when the user has selected a
file.
selectCmd
will be called with one parameter, the filename
selected by the user. When the TixFileSelectDialog widget is created, it
is initially not shown on the screen. Therefore, at line 3, we call its
popup
widget command to place the widget on the screen.
tixFileSelectDialog .file -title "Select A File" -command selectCmd
.file subwidget fsbox config -pattern "*.txt" -directory /usr/info
.file popup
proc selectCmd {filename} {
puts "You have selected $filename"
}
